THOMAS O SPARKS United States Patent 3,452,963 PALLET EXTRACTOR HOOK Albert J. Holst, Sr., 3853 Federer Place, St. Louis, Mo. 63116, and Thomas 0. Sparks, 2636 E. 27th St., Granite City, Ill. 62040 Filed May 10, 1966, Ser. No. 549,435 Int. Cl. B661? 9/18; B66c 1/10 US. Cl. 254-131 4 Claims ABSTRACT OF THE DISCLOSURE Description of the drawings FIGURE 1 is a plan view of the pallet extractor hook, and

FIGURE 2 is a side elevational view partly in detail of the hook shown in FIGURE 1.

Detailed description The pallet extractor hook 10 is made of cast metal or prefabricated rolled metal plate. It is made of sufiicient thickness to withstand the load of the pallet and the tension load as the pallet is pulled by machinery, such as a high lift or winch. Its length is sufficient to provide leverage to raise the pallet from the floor.

The pallet extractor hook 10 comprises a pulling arm 11, having means for engagement with a chain hook or the like on the free end thereof. As shown, the means is an eyelet 12. Attached to the other end of the arm is a substantially U-shaped body 13, which comprises a base portion 14 which is curved so that the undersurface thereof 15 provides a skid for sliding the hook 10 and pallet. The U also includes arm members 16 which comprise a first portion 17 which extends upwardly from the base 14 toward the undersurface of a pallet. Joined to the first portion 17 is a second portion which extends outwardly from the first portion 17 and upwardly toward the undersurface of a pallet. Projecting upwardly from the second portion 18 are pins 19 which are forced into the undersurface of the wooden pallet when tension is applied on the arm 11. The pins 19 are of sufficient strength to hold the load and of suflicient sharpness to penetrate the pallet when tension is applied. The angles between the arm 11 and the base 14 and between the first portion 17 and the second portion 18 of the arms 16 are such that the ice pallet and the load are raised when tension is applied on the arm 11. Preferably the angles are about 102 and about 118 respectively.

In use, the pallet extractor hook 10 is manually inserted under a wooden pallet with the prongs 16 straddling the center member of the pallet. A chain hook is then inserted in the hole 12 in the arm 11. The chain is attached to a winch or other machinery, such as high lift or tractor. Tension is applied to the chain, and the hook 10 raises the pallet and load. Because the pins 19 dig into the base of pallet, the load is borne on the radius 15 between the body 13 and the arm 11, and the pallet and its load may then be pulled away from a crowded area, moving on the outside radius 15. In other words, the hook 10 aids in the removal of pallet loads from crowded tiers of pallets.

What is claimed is:

1. A hook for moving a load bearing pallet comprising:

(a) a pulling arm,

(b) means on the free end of said arm for attachment to a mechanical pulling means,

(c) a body portion on the other end of said arm for engaging the underside of a pallet, said body portion comprising (1) a first section attached to the end of the pulling arm and extending angularly upwardly therefrom toward the underside of the pallet to be moved,

(2) the juncture of the arm and the first section being curved t-o define a skid surface for sliding the hook and pallet,

(3) a second section extending upwardly and outwardly from the first section toward the underside of the pallet to be moved, and

(4) means on the second section projecting upwardly therefrom for engaging the underside of a pallet.

2. The structure of claim 1 wherein the body portion is substantially U shaped with the arms of the U being formed from portions of the first and second sections.

3. The structure of claim 2 wherein the projecting means on the second section are pins projecting from the upper surfaces of the second section and of a sharpness to penetrate the underside of the pallet.

4. The structure of claim 2 wherein the base of the U forms the skid surface.
